Answer:
20/7 dollars per hour
Step-by-step explanation:
He pays 10 dollars per 3 1/2 hours. To find the unit rate, we divide the two.
10 / (3 1/2) =
10 / (7/2) =
(10/1) x (2/7) =
20/7
Answer: 70%
explanation: you would do
42 divided by 60
which would give you 0.7
then you would multiply 0.7 by 100
which would give you 70.
then place a % sign after 70 which would be
70%
So we say x=-2
so in the equation where ever we see x we plug in like
f(-2)= 2 * (-3)^3 + 3 * (-2)^2
= 2 * -8+ 3 * 4
= -4
(-2,-4)
hope that helps
